Jon Gosselin violated an “unambiguous” court order not to comment on his recent legal battle with ex wife Kate to keep their children off TV, Mark Momjian, Kate’s lawyer, told RadarOnline.com exclusively. RadarOnline.com has also learned exclusive details about the secret court appearance that took place October 13.

Jon Tweeted on Friday that he had been back to court to try to keep his kids off TV, saying they were suffering emotional and behavioral issues from their lack of privacy. He revealed that he lost his secret battle.

RadarOnline.com learned that the October 13 court case was a six-hour hearing. One source said Jon’s arguments were ridiculous and the judge certainly wasn’t impressed – giving Kate the right to make the decision about the kids appearing on TV.

While that verdict is in, Kate’s lawyer promised that Jon revealing the private court battle against the judge’s orders is an issue that will continue.

Friday’s Tweet reminded a lot of people of Jon’s actions from last year, when he first said his kids loved being on TV, then said it was bad for them, then allowed it again, tried to get custody from Kate, accused her of being a bad mom for appearing on Dancing With the Stars and generally created chaos.

Momjian told RadarOnline.com about Jon: “He decided to Tweet on a legal proceeding when a court was unambiguous about its order that it did not want it to be discussed.

“Ms. Gosselin is going to adhere to the court’s admonition to keep this matter private.”

On Friday Jon Twittered: “On October 13, 2010, I went to court to act in the best interest of my children- to remove them from television. The judge respectfully denied my plea, and granted filming rights to their mother. I honor the judge’s decision, but I do not support it. I will not stop fighting to remove my children from television. It is not a child’s job to support themselves, or a lifestyle, they need to be kids.”

Jon also said his TLC contract is preventing him from taking other entertainment-related jobs and that he has not been able to find a job outside of the field.

The Gosselin 8 appear on Kate Plus 8, the series of specials that replaced Jon & Kate Plus 8. And while Kate has continued to earn money on reality TV and through her appearance on Dancing With the Stars last season, Jon says he’s struggling.
